Sitting together on a train, traveling through the Canadian Rockies were an American guy, a Canadian guy, a little old Greek lady, and a young blonde girl with large breasts.

The train goes into a dark tunnel and a few seconds later there is the sound of a loud slap. When the train emerges from the tunnel, the American has a bright red hand print on his cheek.

No one speaks.

The old Greek lady thinks: The American guy must have groped the blonde in the dark and she slapped his cheek.

The blonde girl thinks: That American guy must have tried to grope me in the dark, but missed and fondled the old lady and she slapped his cheek.

The American thinks: The Canadian guy must have groped the blonde in the dark. She tried to slap him but missed and got me instead.

The Canadian thinks: I can't wait for the next tunnel, so I can smack the American again.
